Carrier bicycle



FIG. 1 is a rear view of my new design;

FIG. 2 is a top view of my new design;

FIG. 3 is a front view of my new design;

FIG. 4 is a perspective left side view of my new design;

FIG. 5 is another perspective left side view of my new design; and,

FIG. 6 is a left side view of my new design.

The right side views are not depicted as they are the mirror images of the left side views described above. The wheel spokes and tire treads are not shown and are disclaimed.

The broken lines generally showing the bicycle structure illustrate environmental structure and form no part of the claimed design. 

I claim the ornamental design for a carrier bicycle, as shown and described.
